Kelly Clarkson shows off post-baby body!

The American Idol winner, 32, joins ranks of celebrities in taking part in the ALS Ice Bucket Challenge, People reported. The singer subsequently posted a video of herself on her Facebook page, showing off her post-baby body, after giving birth to a daughter named River Rose, last June 12.

Clarkson jokingly said "a ton of mean people" have dared her to get wet in this frigidly cold challenge.

Clarkson had difficulty pouring the bucket of ice cold water over her head, at first, as People reported. After several tries, she got soaked after bathing herself with the freezing cold water.

Kelly and husband, Brandon Blackstock, were wed in October last year in a small ceremony in Tennessee.

The AI champ has never hidden her delight in becoming a new mother, amid showing a new Kelly Clarkson post-baby body. She tweeted this message last July:

"I still can't believe I made a human."

She added the hashtags: "topthat" and "firstglassofwineintenmonths" on her tweet.

Hollywoodlife reported that the singer clearly was into a good cause, and that showing off a Kelly Clarkson post-baby body was just a bonus.

The video Kelly posted on Facebook showed the singer and her husband, Brandon, taking the Ice Bucket Challenge together.

The couple were shown to be having fun playing around after they've got soaked.
